Evidence for atheism

[Jenny A]

There's several different arguments for the existence of a god, i myself have created a topic in religion section about some of my own beliefs few weeks ago, so i'm not exactly going to takeover this thread to talk about those beliefs.

But in sum, and allow me the analogy, God is like an unicorn: it could exist, it's viable, it'd be very reasonable to exist. We might refute that there are unicorns on Earth in the present, but we trully can't refute the existence of a unicorn because it's an entirelly believable possibility, we have several animals with horns, i see no big reason to refute the possibility that there might be unicorns horse somewhere, even on a parallel dimension.
The same as god, it's entirelly believable that there is eternity and something trully uncreated existing, i see no reason to believe otherwise in fact. That that thing might be a god or just the "universe" in it, it's open to interpretation, but there's trully no reason to object the possibility.

It's essentially impossible to prove a negative. But some things are so improbable that we can safely treat them as disproven.

We can't disprove unicorns. A horse or deer-like animal isn't an physical impossibility. Fair enough. But that's no reason to assume that unicorns exist, merely an argument that could possibly exist. Now, consider the evidence for unicorn's existence: Narr Whale horns, contradictory written reports in bestiaries, myths. Not good. Given the lack of other evidence I can safely hold unicorns lack of existence significantly more probable than their existence.

Now lets look at the possibility of an "uncreated existing." First of all either matter and energy have always existed or they came into existence at some point in time or various points in time. Is it impossible that there was an always existing creator or a creator who suddenly sprang into existence who made everything else out of nothing? I can't disprove that notion, but it's a considerably more complicated idea than either that everything always existed or that everything spontaneously came into existence. Why? Because it presumes the eternal existence of a being infinitely more complex than atoms. It also adds a second and unnecessary step to the process. There is no evidence whatsoever of such a being. Therefore I find such a being much less probable than a unicorn. Therefore I can dismiss the idea of a "uncreated existing."

Further, even if you could prove that universe was created by such a being, you'd still have to show that it's extant today. Good luck with that.
